α-Solanine promoted the apoptosis of U87MG cells. a-c Ratios of total apoptosis and early apoptosis in U87MG cells treated with α-solanine at concentrations of 0 µM,10 µM,15 µM, respectively, were examined based on flow cytometric detection. d The histogram shows the percentage of early apoptotic cells in different treatment groups. The error bars represent the standard error (n = 3). * P < 0.05
